But Lacazette came off the bench and settled the game with a clever near post finish and a header.

Fellow subs Rob Holding and Eddie Nketiah also found the net late on to add gloss to the result.

Here is how Arsenal rated in Singapore...

Arsenal

Bernd Leno 8

Showed intelligent positioning to cut out a series of crosses and then showed off his shot stopping ability to deny Weah. Looks a really good addition to the Gunners squad.

Hector Bellerin 6

Fine performance, but nothing to write home about. Sensible defensively, albeit hardly tested, but didn't get forward as much as he would like.

Sokratis 6

A couple of vital interceptions and brings more calm to the Gunners defence. A few more weeks, when he has fully settled, and Emery will start to see the best of him.

Shkodran Mustafi 5

A step off the pace in the early stages but grew into the half, which coincided with the nullifying of the dangerous Weah.

Sead Kolasinac 5

Really struggled against Weah throughout and wasn't a surprise when he gave away the clear cut penalty. Also allowed Toufiqui to cut off the right flank at will. Looked the weak link.

Matteo Guendouzi 8 MOTM

The Frenchman might be the recruit of the summer. He possesses an unbelievable passing ability, with positional sense to cut out any danger. If you squinted and ignored the flowing locks, you could be duped into thinking you were watching 2008-era Xavi.

Mohamed Elneny 7

Sat deep and looked infinitely better than at any point last season. If he continues this trajectory, then Emery could be facing some difficult midfield decisions.

Mesut Ozil 8

Captain fantastic! Took his goal really well. But what stood out was his all-round play, especially his linking with Guendouzi and his early balls over the top. Back in business and shrugging off the haters.

Henrikh Mkhitaryan 7

Seemed to be everywhere. When in possession always appeared to pick the right next move. Often utilised his quick feet to look up and unleash Aubameyang.

Alex Iwobi 6

Lively but end product still a massive worry. Had the best first half chance, other than the goal, and struck straight at Buffon.

Pierre-Emerick Aubameyang 8

So. Much. Pace. You get the feeling the second half of last season was merely an amuse-bouche for his season's main course. Premier League defenders be wary, he's coming to get you.

Subs

Emiliano Martinez 6

Dealt with a powerful free kick early on. Couldn't do much to save penalty. (on at h/t)

Aaron Ramsey 6

Didn't stand out as much as the first half performers. (on at h/t)

Alexandre Lacazette 8

Off the bench and proved to Emery why he shouldn't be there when the Premier League season kicks off. Took both finishes well. Lacazette vs Aubameyang could be an interesting battle for the central forward role. (on at h/t)

Eddie Nketiah 6

Showed some of his electric footwork and pace in cameo. Got in on the scoring late on. (on after 63mins)

Reiss Nelson 6

Delivered corner for Holding's goal and set up Nketiah. Bright. (on after 63mins)

Emile Smith Rowe 6

Stand out youngster from the tour so far after his goal last time out. Added an assist for Lacazette's first here as well. Looks talented. (on after 63mins)
